ELLIS BARTHOLOMEW, 0F TOLEDO, OHIO, ASSIG-NOR TO THE NATIONAL FEAT REFINING COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF DELAWARE.

APPARATUS FOR OBTAINING FEAT.

Application filed December 22, 1913.

To all whom it may concern.' Y

Be it known that 1, ELLIS BAnTHoLoMEw, a citizenof the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Apparatus for Obtaining Peat; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this speciicatien.

My invention relates to apparatus for eX- tracting the commercial products contained in pea It consists in providing a' means for forming coke from peat and collecting the gases, oils and the volatile ingredients con tained in the peat.

The apparatus usable in the conduct of the process may be of different forms and still such modifications will contain my invention; also the use of my invention may be involved in the conduct of many processes.

In order to show that the invention is practical, I have selected anapparatus, as an illustration of apparatuses containing I'ny invention and shall describev it hereiny after. The apparatus selected is illustrated in the drawings, in which,-4

Figure 1 is a Vertical sectional view of a separator. Fig. 2 is a sectional view of the separator shown in Fig. 1, taken at right angles to the View shown in Fig. 1.`

Referring tc Figs. 1 and 2, 1 is a large container or bin, suitably supported, for containing peat. The peat is placed in the container or ybin 1 through the hopper 2 located in the top of the bin. The opening v in the hopper 2 is sealed by means of a plate 3. The. bin 1 is provided with a. screw con* Veyer 4, which is operated by means of a 4cogwheel 5 or belt-wheel, which is driven by a suitable power mechanism. The bin 1 is provided with a mouth 6 through which the peat may be conveyed.

The bin is connected to the separator 10 by means o1 a. coupler 11 having right and left handed threads. The coupler 11 is screwed in the mouth 6 of the bin and the top 12 of the separator 10.' The top r12-i's secured to the body of the separatorvlQ by Specification of Letters Patent.

means of screws or bolts 13. The top 12 is provided with a petcock 14 to allow escape of gases or air, as may be desired. An in ner cylindrical shell 15 is located within the hopper being located near the grate and the openings 39 being located above the mouth of the hopper and near the upper part of the hopper, the gases and vapors readily pass outthrough the openings 39 as they are formed or liberated by the heat of the grate The lower end 21 of the separator 10 is contracted and contains the heater 20 and a screw conveyer 22. The heater 20 consists of a plurality of bars 23 forming a grating below the hopper 18. The rods 23receive the peat from the shell 15. They are supported on conductors 24, which are connected to electric connectors 25. The connectors 25 are insulated from the body of the separator 1U by means of fiber plates 26. They are sealed Vin the separator 10 by means of the packing boxes 27.

The screw conveyer 22 is located below the bars 23 and as the peat is turned into coke by the intense heat of the rods 23, the coke falls to the conveyer 22. The lower end of the separator 10 is provided with a mouth 23. The coke is conveyed by the screw conveyer 22 to the mouth 28 through. which it falls into a receptacle or bin 29. The separator l0 is connected with the bin 29 by means cfa coupler 30 for right and left handed threads. The conveyer may be operated l. by means of the pulley 35 or by any other suitable means. A stirrer 31 may baprovided yfor preventing the peat from packing in the shell 15 and for working the coke ofiE the rods 23. The stirrer has a shaft through the openings 39. The mouth of the hopper 18 of the shell 15. The stirrer 31 rise and pass up around the outside of the shell l5. rlhe coke, which is formed by the heat produced by the rods 23, falls to the bottom of the separator 10 and is conveyed to the container 29, the shaker 33 constantly Working the peat down to the heater 23 and causing it to knock and Work od' the coke.

rlhe coke may be removed from the bin 29.

through the sealed door 37 and 38 located at the bottom ot the bin. rlhe plate 37 sets into a iiarinp; flange 38 surrounding the opening; this tightly closes the opening.

The gases and heavy vapors separated from the peat and driven ott' by the heat, pass through one or more outlets 39 arranged around the hopper and below the lower or delivery end thereof. The outer surface of the hopper directs the ,eases and vapors to the outlets 39. rlhey are directed into a. suitable collector wherein the heavy liquids such as tar are collected and are immediately condensed and fall to the bottom of the collector. The gases and the vapors of the lighter liquids pass on and are separated. puriiied and collected in suitable apparatus and reservoirs.

ln order to obtain a suitable balancing pressure in the system of which the separator forms a part and in order to fill the system 'with a gas similar in character to that produced by the heater 23 in the separator 10 and to drive all air out of the systeni. a. reservoir for one of the gases col lected is connected to the bin l by means of a pipe l0 'which is provided With'a valve il and a clap-valve 42. The clap-valve 42 prevents automatically any return of the gas t-o the reservoir from the bin l.

rlhe heater 23, is connected to a source 50 of current by means of the conductors 5l. Any suitable arrangement may be made for connecting the heaters with a source of current. T hey may be connected to a 'stepdown line transformer Wound for producing large amperage. rl`he conductor 51 may also contain suitable switches and electrically controlled and protective devices, what l have shown being merely a conventional illustration of a means for directing an electric current through the heater 23.

lThe apparatus selected and described may be ,greatly varied in the arrangements and order of their parts and in the substitution of elements having' equivalent functions nieces? Without departing from the spirit of the invention.

Having;` thus described my invention, what li claim as new, and desire to secure by lietters Patent, is,- A

l. ln a separator. the combination of an outer and an inner shell having a hopper at its lower end the two shells being located in spaced relation. a stil-rer contained in the shell, a grate heater located beneath the lower end oil the shell. the separator having' outlets located around and above the deliv-A ery end of the hopper, the space between the shells of the separator adapted to be filled with the `eas arising around the hopper.

2. ln a separator, the combination of an inner and outer shell. the lower end of the inner shell `forming),` a hopper and a 2tirate of electrodes located belouv and near the hop per to form a clear annular space for collecting the gases, the outer shell having' an outlet for rases and vapors located beside the hopper above the grate.

3. ln an apparat-us for separating; peat products, the combination of two bins and a separator hermetically sealed, the separator connected between the bins, a conveyer for conveying` the contents of one bin to the separator, the separator having' a hopper and a stirrer, a grate oli electrodes for receiving the contents of the separator through the hopper, ay conveyer for directing the material from the grate to the second bin. means for directing some of the njas formed at the grate, 'through the separator and to the bin from which material is received by the separator.

il. ln an apparatus for separating peat products, the combination of tvf'o bins and a separator hermetically sealed, the separator connected between the bins, a conveyer for conveying the contents ot' one bin to the separator,l the separator having: an inner shell, the shell having a hopper at its lower end and a stirrer, a grate of electrodes Jfor receivingr the material from the separator through the hopper., located close to the hopper, and forming a clear annular space for collecting the gases formed at the grate. the outer Wall ot the separator having: outlets located above the lower edge of the hopper, a conveyer for directing the material from the separator to 'the second bin.

ln testimony whereof, l have hereunto signed my name to this specification in the rn'esence of two subscribing witnesses.
